Three Green Comets to Grace earth Skies in Coming Months, One visible to the Naked eye
Jakarta - Skywatchers are in for a rare treat as three newly discovered comets – all exhibiting a distinctive green hue - will make their closest approaches to Earth in the coming months. Thes celestial visitors, designated C/2025 A6 Lemmon, C/2025 R2 Swan, and C/2025 K1 Atlas, were all identified this year and promise a impressive show for those looking up.
The most anticipated of the trio is C/2025 A6 Lemmon,predicted to become shining enough to be visible without the aid of binoculars or a telescope. This comet will reach its closest point to Earth on October 21st, offering optimal viewing conditions as its brightness peaks. It will then make its closest approach to the sun on November 8th. Initially, lemmon wasn’t expected to be especially luminous, but a rapid increase in brightness observed in August suggests a perhaps stunning display. While it may not rival the magnitude of the 1997 “great Comet,” experts believe it will be the most impressive comet visible this year.
Discovered just weeks ago, on the very day it reached its closest point to the sun, C/2025 R2 Swan was initially obscured by solar glare. Detected by the Swan instrument aboard NASA’s Solar and Heliospheric Observatory (SOHO), this comet will now be moving away from the sun but closer to Earth, reaching its closest approach on October 20th at a distance of 39 million kilometers. While not as bright as Lemmon, a slight magnification will be helpful for clear viewing.
C/2025 K1 Atlas, though less luminous than the other two, will become brighter as it nears its closest approach to the sun and is expected to be best observed in the weeks ahead before dawn.
